Add k8s ingress and metallb features

- enable ingress-nginx and metallb features
  for the configurations:
  - cookiecutter-context-k8s-sl
  - cookied-cicd-k8s-genie
  - cookied-bm-k8s-contrail

- add 'external' network on cfg, ctl, cmp and prx nodes

- enable DHCP in 'external' network for auto configuration
  of the external interfaces

- get the status of the ingress and metallb features from
  the salt pillar instead of environment variables to
  run the tests on the existing deployments
